OEIS Sequences

Image of primes (A000040) under "little Hankel" transform that sends [c₀, c₁, ...] to [d₀, d₁, ...] where d_n = c_n² - c_n+1*c_n-1. A56221

G.f.: A(x,q) = sqrt( Q(x,q) / Q(x,-q) ), where Q(x,q) = ∑_n=-oo..+oo (x - qⁿ)ⁿ. A292929

Row 2 in rectangular array A292929. A294065

Array: row n shows the coefficients of the characteristic polynomial of the n-th principal submatrix of A115255 (in square format); by antidiagonals. A203005

Expansion of b(x)² * b(x²) / b(x⁴) where b is a cubic AGM θ function. A321528

Square array A(n,k), n >= 0, k >= 0, read by antidiagonals downwards, where column k is the expansion of B(x)^k, where B(x) is the g.f. of A384898. A384903

a(0) = 1, a(1) = 2, a(2) = 5; for n >= 3, a(n) = a(n - 1) - 2·a(n - 2) + a(n - 3). A121311
